In recent years, the smart terminal device market such as smart phones and tablet computers is developed vigorously. Before the delivery of smart terminal devices such as smart phones, CE/FCC certification is usually required, which not only needs to perform radio frequency coaxial line assembly detection, but also needs to detect whether SAR (Specific Absorption Rate, electromagnetic wave Absorption ratio) exceeds standard. The existing SAR measuring methods can be roughly divided into two types, one is a temperature induction method, and the other is an electric field intensity measuring method; the field strength measurement method is commonly used in the industry to measure the damage of electromagnetic radiation to human body. Most of smart phones in the current market adopt an SAR sensor scheme for power detection, and when the sensor detects that a human body approaches, the power of the mobile phone is reduced to protect the human body; therefore, a mobile phone adopting the scheme must include an SAR sensor (sensor) or avoid a hot spot area of SAR through antenna design; however, the effects of SAR cannot be completely eliminated by tuning the antenna.

The user device includes, but is not limited to, a terminal device such as a smartphone, a tablet computer, a personal computer, and the like, and the network device includes, but is not limited to, a network host, a single network server, a plurality of network server sets, or a cloud computing-based computer set. Here, the Cloud is made up of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a type of distributed Computing, one virtual computer consisting of a collection of loosely coupled computers.
Fig. 1 is a schematic structural diagram of a radio frequency coaxial line assembly detection device for an intelligent terminal device according to an embodiment of the present application, where the device includes a test power supply module, a GPIO detection module, and a lower ground inductor module; the testing power supply module and the GPIO detection module are connected with a small plate coaxial seat of the intelligent terminal device, and the underground inductor module is connected with a main board coaxial seat of the intelligent terminal device.
For example, when an antenna is disposed at a low end or a distance greater than 50mm, for smart terminal devices such as a smart phone and a tablet computer, a radio frequency coaxial line is assembled to reduce radio frequency conduction loss. The radio frequency coaxial line is used for connecting a mainboard coaxial seat and a small plate coaxial seat of the intelligent terminal equipment, and is provided with a shielding layer, and the impedance can be 50 omega. Taking a smart phone as an example, the main set antenna of the smart phone is connected to the small board through a coaxial line.
In some embodiments, the test power supply module and the GPIO detection module are connected to a small board coaxial base of the smart terminal device through a Flexible Printed Circuit (FPC).
In some embodiments, the test power module is configured to provide 1.8V power. For example, the coaxial line is simultaneously connected with the 1.8V power supply provided by the test power supply module. As shown in fig. 2, the 1.8V power supply is a long power supply provided by the system of the intelligent terminal device. In some embodiments, the selectable range of the power supply voltage provided by the test power supply module is 1.2-2.8V.
In some embodiments, the lower ground inductance module employs an 82nH inductance. For example, as shown in fig. 2, one 82nH is reserved for sensing the ground; the low level can be measured under the condition that the coaxial line connecting the main board and the small board is well buckled; under the condition that the coaxial line between the connecting main board and the small board is pulled out, the high level can be measured. In some embodiments, the lower ground inductance module has an inductance selectable in a range of 68nH to 100 nH.
In some embodiments, the GPIO detection module is configured to detect a current level state, wherein the current level state is a high level state or a low level state.
For example, since GPIO (General Purpose Input/Output) has an interrupt property, the interrupt property of GPIO can be used to continuously interrogate the high-low state of the coaxial line at the bottom layer. The GPIO interrupt signal can be provided by a CPU of the intelligent terminal device. As shown in fig. 2, when the coaxial line connection is normal, the 1.8V power supplied by the test power supply module is pulled down by the 82nH inductor of the lower ground inductor module, and becomes low level, which is detected by the GPIO detection module.
In some embodiments, if the current level state detected by the GPIO detection module is the low level state, the intelligent terminal device is considered to be in an overall state, where the overall state is a state in which coaxial lines connecting the motherboard coaxial base and the platelet coaxial base are closed; and if the GPIO detection module detects that the current level state is the high level state, the intelligent terminal device is considered to be in a non-complete machine state, wherein the non-complete machine state is a state in which the coaxial line connecting the mainboard coaxial seat and the small plate coaxial seat is disconnected.
For example, as shown in fig. 3, after the intelligent terminal device is powered on, the GPIO detection module starts to perform detection by using the interrupt attribute of the GPIO, and determines the high-low level state. For example, the decision logic may be set to: the low level is Ture, the code logic is judged to be 0, and the state of the whole machine is judged; the high level is False, the code logic is judged to be 1, and the state is judged to be not the complete machine state. Here, the overall state may refer to: the main board is connected to the small board through FPC and radio frequency coaxial line to assemble the sample machine. When the GPIO detection module detects a high level (the coaxial line is disconnected), the state is a non-complete machine state, and when the GPIO detection module detects a low level (the coaxial line is buckled), the state is a complete machine state.
In some embodiments, if the GPIO detection module detects that the current level state is the low level state, it is determined that the intelligent terminal device is in the complete machine state, and the antenna transmission power of the intelligent terminal device is reduced.
For example, if the conduction in the high state is 23dBm, and the conduction in the low state is reduced to 21dBm, the SAR detection reaches the standard. When the GPIO detection module detects a low level state, the intelligent terminal device is judged to be in the complete machine state, and the preset power reduction parameter is called to reduce the antenna transmitting power of the intelligent terminal device, so that the SAR value after the power reduction does not exceed the standard. And if the GPIO detection module detects that the current level state is the high level state, the intelligent terminal device is considered to be in the non-complete machine state, and the antenna transmitting power of the intelligent terminal device does not need to be reduced.
Fig. 4 is a flowchart of a radio frequency coaxial line assembly detection method for an intelligent terminal device according to an embodiment of the present application, where the method includes step S401 and step S402.
Step S401, detecting a current level state through a GPIO detection module, wherein the GPIO detection module is connected with a small plate coaxial seat of the intelligent terminal device, and the current level state is a high level state or a low level state; step S402, if the GPIO detection module detects that the current level state is the low level state, the intelligent terminal device is considered to be in a complete machine state, wherein the complete machine state is a state that a coaxial line connecting the mainboard coaxial seat and the small plate coaxial seat is closed.
For example, the test power supply module and the GPIO detection module are connected to a small board coaxial socket of the intelligent terminal device, and the underground inductor module is connected to a main board coaxial socket of the intelligent terminal device. The radio frequency coaxial line is used for connecting a mainboard coaxial seat and a small plate coaxial seat of the intelligent terminal equipment.
Since the GPIO (General Purpose Input/Output) has the interrupt property, the high-low level state of the coaxial line can be continuously queried at the bottom layer by using the interrupt property of the GPIO. The GPIO interrupt signal can be provided by a CPU of the intelligent terminal device. As shown in fig. 2, when the coaxial line connection is normal, the 1.8V power supplied by the test power supply module is pulled down by the 82nH inductor of the lower ground inductor module, and becomes low level, which is detected by the GPIO detection module.
As shown in fig. 3, after the intelligent terminal device is powered on, the GPIO detection module starts to perform detection by using the interrupt attribute of GPIO to determine the high-low level state. For example, the decision logic may be set to: the low level is Ture, the code logic is judged to be 0, and the state of the whole machine is judged; the high level is False, the code logic is judged to be 1, and the state is judged to be not the complete machine state. Here, the overall state may refer to: the main board is connected to the small board through FPC and radio frequency coaxial line to assemble the sample machine. When the GPIO detection module detects a high level (the coaxial line is disconnected), the state is a non-complete machine state, and when the GPIO detection module detects a low level (the coaxial line is buckled), the state is a complete machine state.
In some embodiments, the radio frequency coaxial line assembly detection method for the intelligent terminal device further includes: and if the GPIO detection module detects that the current level state is the high level state, the intelligent terminal device is considered to be in a non-complete machine state, wherein the non-complete machine state is a state in which the coaxial line connecting the mainboard coaxial seat and the small plate coaxial seat is disconnected.
In some embodiments, the radio frequency coaxial line assembly detection method for the intelligent terminal device further includes: and if the GPIO detection module detects that the current level state is the low level state, the intelligent terminal device is considered to be in the complete machine state, and the antenna transmitting power of the intelligent terminal device is reduced.
For example, when the GPIO detection module detects a low level state, the intelligent terminal device is judged to be in the complete machine state, and a preset power reduction parameter is called to reduce the antenna transmitting power of the intelligent terminal device, so that the SAR value after the power reduction does not exceed the standard. And if the GPIO detection module detects that the current level state is the high level state, the intelligent terminal device is considered to be in the non-complete machine state, and the antenna transmitting power of the intelligent terminal device does not need to be reduced.
In summary, the embodiment of the application realizes the radio frequency coaxial line assembly detection by using a simple circuit structure, and judges whether the intelligent terminal device is in a complete machine state. Compared with the prior art, the SAR sensor (sensor) does not need to be assembled, the cost is low, and the practicability is high. Further, in the embodiment of the application, when the intelligent terminal device is detected to be in the complete machine state, the antenna transmission power of the intelligent terminal device can be reduced, so that the SAR is reduced, the harm of electromagnetic radiation to a human body is reduced, and the use safety of a user is ensured.
